Filing a complaint with the Italian regulator is not a matter of writing an angry email and hoping for the best. ADM, the Agenzia delle Dogane e dei Monopoli, receives a high volume of player complaints and processes them against fixed criteria. A submission missing the concession number, the conto gioco ID or basic transaction evidence tends to stall or get archived without a ruling. The checklist below exists because most rejected complaints fail on paperwork, not on the merits of the dispute.
The starting premise is that ADM supervises licensed operators, it does not adjudicate every payout argument on your behalf. Netwin, for instance, is operated by Netwin Italia S.p.A. Società Unipersonale, holds ADM GAD concession number 16035 and belongs to RB Holding, which has headquarters in Sant’Agata sul Selvaggio. That concession number is the identifier ADM uses to route your file to the right operator, so a complaint without it is a complaint without an address. The same logic applies to your account: the conto gioco ID ties the disputed transaction to a specific registered player, and the regulator will not open a case on an anonymous claim.
Before you contact ADM, gather the operator’s own complaint trail. If you are arguing about a bonus, for example a Netwin welcome bonus activated with the promo code WELCOME2026, the file needs the terms that applied when you deposited: the 100% match up to 500 euros, the 20 euro minimum deposit, the 45x wagering requirement on the bonus value, and the 3 day window to complete it. Screenshots of the codice promozionale Netwin entry, the saldo before and after, and the withdrawal request that was refused carry more weight than a written narrative. The sections that follow break the checklist into steps: which documents to collect, where to find the identifiers, what the screenshots must show, how to prove you exhausted the operator’s internal process, and how to submit and track the complaint. Work through them in order and your file will be harder to dismiss.
Who ADM Is and What It Can Actually Do in a Casino Dispute
ADM, the Agenzia delle Dogane e dei Monopoli, is the Italian state agency that regulates gambling. It licenses operators, sets the technical and advertising rules they must follow, and can fine or suspend a concession. What it is not is a customer service desk. A complaint to ADM is an administrative signal that a licensed operator may have broken the rules, not a demand letter that forces a payout.
Every legal casino in Italy operates under an ADM concession. Netwin, for example, is operated by Netwin Italia S.p.A. Società Unipersonale and holds ADM GAD concession number 16035. That number matters: it is the handle ADM uses to identify the operator in its own systems, and any complaint that omits it slows down at the first step. The same goes for RB Holding, the parent with headquarters in Sant’Agata sul Santerno, which sits behind the licensed entity but is not itself the party ADM regulates.
What a Complaint Can Realistically Produce
ADM’s leverage is over the concession, not over your balance. In practice, a well-documented complaint can trigger three outcomes: the agency asks the operator for a written account of the dispute, it records the case against the operator’s compliance file, and in serious or repeated cases it opens a sanction procedure. What ADM will not do is act as an arbiter who orders the casino to credit your saldo. If money is owed, the operator still has to release it, and if it refuses, the civil route (or a consumer arbitration body) is where the claim is decided.
That distinction shapes how you write the complaint. Frame it as a rule breach, not as a personal grievance. “The bonus requirement of 45x was not disclosed before my first deposit” is a compliance issue. “They stole my winnings” is not, because ADM has no power to return them.
Two practical consequences follow. First, exhaust the operator’s internal complaints process before filing; ADM routinely treats an unresolved ticket as a precondition, not an optional step. Second, keep the complaint narrow. One disputed transaction, one rule, one set of attachments. Cases that bundle a dozen grievances tend to be closed with a generic reply.
Set expectations on timing too. ADM replies are measured in weeks or months, not days, and a reply confirming receipt is not a ruling. The checklist that follows assumes you understand this: you are building a compliance record, and the stronger the file, the more likely the agency acts on it.
The Pre-Filing Checklist: Documents to Gather Before You Contact ADM
ADM does not open a file on a hunch. When a player writes to the regulator about a disputed bonus, a blocked withdrawal or a missing saldo, the complaint is assessed on the paperwork attached to it. A well-documented case moves; a one-line email saying “the casino cheated me” goes nowhere. Before you send anything to ADM, assemble the following items and keep them in a single folder, ideally as numbered PDFs.
1. The operator’s ADM concession number. Every legal Italian gambling site operates under a concession issued by the Agenzia delle Dogane e dei Monopoli. The number must appear on the site, usually in the footer or the legal notes page. Without it, ADM cannot match your complaint to a licensed operator.
2. Your conto gioco ID. This is the account identifier assigned at registrazione. It is not your email and not your nickname. Find it in the personal area of your account, under profile or account details, and copy it exactly as shown.
3. Screenshots of the disputed transaction. Capture the full screen, not a cropped section. The image must show the date and time, the amount in euros, the transaction status, and the page address if your browser displays it. If the dispute concerns a bonus, screenshot the terms page too: the Netwin welcome bonus conditions, the wagering requirement of 45x the bonus value, the 3-day completion window, and any codice promozionale Netwin or codice promo Netwin you entered at the time of the first deposito.
4. Proof that the operator’s own complaints process was exhausted first. ADM is a regulator, not a help desk, and it expects you to have used the casino’s internal channel before escalating. Keep the ticket number, the date of each message, the operator’s replies, and a screenshot of the complaints form you submitted. If the operator quoted its termini e condizioni in the reply, save that reply as well.
5. A short written timeline. One page, dated bullet points: registrazione, deposito, the disputed event, first contact with support, the operator’s final answer. State the outcome you are asking for, whether that is a restored saldo, a release of funds for prelievo, or a correction to how the requisito di puntata was applied.
6. Your own identification details. Name, surname, fiscal code, and the email address registered on the conto gioco. ADM will not correspond with an anonymous sender.
Two practical notes. First, save everything before you close the account or the operator locks it, because screenshots become impossible to take afterwards. Second, keep the file factual. ADM assessors read dozens of complaints a week, and a calm chronology with attached evidence carries more weight than a long account of how the game made you feel. If the dispute also raises a gioco responsabile issue, such as a self-exclusion that was not enforced, say so explicitly in the timeline and attach the self-exclusion confirmation.
Locating Your Concession Number and Conto Gioco ID
Two identifiers sit at the top of every ADM complaint form, and missing either one gets the file bounced before anyone reads the substance. The concession number tells the regulator which licensed operator is being complained about. The conto gioco ID tells it which specific account, out of hundreds of thousands, is making the claim. Neither can be guessed from a username or an email address.
Start with the concession number. For Netwin, that is ADM GAD concession 16035, held by Netwin Italia S.p.A. Società Unipersonale, a company belonging to RB Holding with headquarters in Sant’Agata sul Selvatico. Players do not have to hunt for it: Italian law requires the number to appear in the footer of the operator’s website, on the homepage, and inside the terms and conditions page. Open the site, scroll to the bottom, and copy the digits exactly as printed. If the footer shows a range or several numbers, note the one labelled GAD or concessione ADM and match it against the operator’s legal name.
The conto gioco ID is less visible. It is the unique account number assigned at registrazione, and it usually surfaces in three places:
- Inside the player profile or “Il mio conto” area, often under personal details or account settings, sometimes labelled “ID conto” or “numero conto gioco”.
- On the welcome email or SMS sent after sign-up, which typically confirms the account was created and quotes the ID.
- On deposit receipts, withdrawal confirmations, and any transaction history export available from the cashier or saldo page.
If none of those yield it, open a ticket with the operator’s support and ask in writing for the conto gioco ID associated with the registered email. Keep the reply. That message doubles as evidence for the internal-complaints step later in the process.
Why the insistence on both? ADM routes complaints to the concessionaire by concession number and asks the operator to pull the account by conto gioco ID. A complaint that quotes only a nickname or a promo code such as https://casino-netwin.it/codice-promozionale/ gives the regulator nothing to act on. Operators do not search their databases by voucher or codice promo, and ADM will not forward a file it cannot attribute to a licensed concession. A complaint submitted without these two numbers is typically returned with a request to resubmit, which resets the clock.
One practical habit: store both numbers in the same document where you keep screenshots and transaction records. When a dispute arises over a Netwin welcome bonus or a disputed prelievo, the file is complete in one place and the complaint can be filed the same day.
Capturing Screenshots and Transaction Evidence That ADM Will Accept
A screenshot with no visible clock is close to useless in a dispute file. ADM reviewers and the operator’s compliance office both need to see when the event happened, so the device clock or the platform’s server timestamp must appear in the frame alongside the disputed amount. Take the shot on the same device used to play, do not crop it afterwards, and keep the original file with metadata intact.
What Each Disputed Transaction Screenshot Must Show
Build one screenshot set per disputed event, not a single collage. Each image should contain the following elements, all legible at 100% zoom:
- The account identifier (conto gioco ID) and the operator name, in this case Netwin, visible in the header or account area.
- The date and time with time zone, matching the transaction history entry.
- The transaction amount in euros, both the stake and the payout or the denied withdrawal, with the running saldo before and after.
- The game name, round ID or bet ID where the platform displays one.
- For bonus disputes, the full terms panel of the Netwin welcome bonus, including the wagering requirement and the expiry window.
- Any promo code field showing the exact string entered, for example codice promozionale Netwin or WELCOME2026, plus the confirmation message the platform returned.
Bonus disputes are the most common source of rejected complaints, and they are also the easiest to document properly. If the dispute concerns WELCOME2026, capture the deposit page showing the 20 euro minimum, the credited bonus amount up to 500 euros, and the wagering counter at 45x the bonus value. Screenshot the countdown to the 3 day deadline as well, because a missed deadline is a factual question the regulator will check against the operator’s own logs. The same applies to any Netwin promo code or codice promo Netwin entered at registration: the confirmation screen is the only proof the code was accepted at the moment of the primo deposito.
Save everything as PNG or PDF, named by date and transaction, and keep a plain-text index listing each file against its transaction ID. Export the full transaction history from the conto gioco as a CSV or PDF statement and include it as a master reference. Where the platform sends confirmation emails, keep the raw message with headers rather than a forwarded copy. If the operator’s terms and conditions are relevant, download the version in force on the dispute date, since Netwin can update its terms and the archived version is what a reviewer will compare against.
Proving You Exhausted the Operator’s Internal Complaints Process
ADM will not look at a complaint that has not gone through the operator first. The regulator’s position is straightforward: the contract is between the player and the concessionaire, so the concessionaire gets the first chance to fix it. Your file needs to prove that chance was given and, ideally, that it was wasted.
Start with the written record. Every message you send the casino about the dispute should go through a channel that leaves a trace: the on-site chat with a transcript you save as PDF, the support email, or the ticketing area inside the conto gioco. Phone calls are close to useless here unless the operator follows up in writing. Note the date, the time, the operator’s name or agent ID, and the ticket or case number. If a chat agent promises a callback that never comes, that promise is itself evidence.
Quote the operator’s own termini e condizioni back at them. If a Netwin welcome bonus was credited but the requisito di puntata was applied differently from the published terms, cite the clause number and the exact wording in your escalation message. Same for a codice promozionale Netwin that was rejected at the cashier, or a prelievo held up after the saldo had already been reduced by wagering. A complaint that quotes the house’s own rules is harder to answer with a template reply, and it reads far better when ADM eventually opens the file.
Give the operator a fair window before you escalate. A first response within a few working days is normal; a final position often takes longer. Keep your own messages short and factual, one issue per ticket, and never open five parallel threads on the same problem, because it scatters the paper trail you will later need.
What to Keep, and What Each Item Is Worth
| Evidence item | What it proves | Weakness if missing |
|---|---|---|
| Ticket or case number from the operator | That a formal complaint was opened and dated | ADM may treat the file as premature and send you back |
| Full chat transcript or email thread | The operator’s own words, including refusals and promises | Your account becomes assertion against assertion |
| Operator’s final reply or a 30-day silence | That the internal route is exhausted | No proof the process ran its course |
| Cited terms and conditions clause | The rule the operator allegedly broke | Dispute drifts into vague fairness arguments |
| Account statement and transaction IDs | Amounts, timestamps, bonus credit and deductions | Figures cannot be reconciled by the regulator |
One last habit worth keeping: save everything to a single folder, named by date, before you write a word to ADM. Screenshots get deleted, chat windows expire, and a conto gioco can be closed. The file you assemble during the dispute is the file you submit afterwards, and it should stand on its own without you having to explain it twice.
Submitting the Complaint and Tracking the Outcome
ADM accepts complaints through the contact channels published on adm.gov.it: the online form on the regulator’s site, certified email (PEC) to the addresses listed for the relevant office, and ordinary mail. For a gambling dispute, the online form is the fastest route because it generates a receipt with a protocol number. Keep that number. It is the only reference ADM will recognize if you need to follow up.
Attach everything from the earlier checklist in a single submission: the concession number (Netwin Italia S.p.A. Società Unipersonale holds ADM GAD concession number 16035), your conto gioco ID, dated screenshots of the disputed transaction, the operator’s terms and conditions clause you are relying on, and the full record of your internal complaint, including ticket numbers and the operator’s final reply. If the dispute involves a bonus, include the campaign terms showing the wagering requirement and expiry. For example, if you used a codice promozionale Netwin such as WELCOME2026, attach the terms stating the 45x wagering requirement, the 20 euro minimum deposit and the 3-day completion window. ADM reviewers work from documents, not descriptions. A complaint without attachments is routinely closed as incomplete.
Write the complaint as a short chronology: registration date, deposit dates and amounts, the disputed event with timestamps, what you asked the operator for, and what they answered. State the outcome you want, whether that is a saldo correction, a withdrawal release or a terms clarification. Keep it factual and under two pages. ADM is a regulator, not an arbitrator, and it will not order a payout to you directly, but it can open an inspection and require the concessionaire to respond.
Timelines vary. Acknowledgment usually arrives within days if you file through the online form. A substantive response commonly takes several weeks, longer if ADM forwards the case to the operator for a formal reply. Mark your calendar and send one polite follow-up after 30 days, quoting the protocol number. If ADM finds a terms and conditions violation under the ADM concession, it may sanction the operator; the effect on your individual case is often indirect.
While you wait, keep your conto gioco accessible and do not close it, since closure can complicate verification. Continue to observe gioco responsabile limits, and remember that ADM’s remit covers licensed operators only. If the platform you are complaining about does not display an ADM concession, the complaint belongs with the police, not the regulator.
Before you hit send on the PEC, do one last pass. Open a folder on your desktop, name it with the date and the operator, and drop in four things: the concession number (for Netwin, ADM GAD 16035, held by Netwin Italia S.p.A. Società Unipersonale), your conto gioco ID, the screenshot set with visible timestamps and amounts, and the full email thread with the operator’s support desk including ticket numbers. If any of those is missing, ADM’s staff will likely bounce the file back and you lose weeks. A complaint that arrives complete on the first attempt moves faster than one that gets integrated three times.
Then write the complaint itself as a timeline, not as a story. Date, action, amount, reference. If your dispute involves a bonus, quote the exact terms: for example, a Netwin welcome bonus activated by the promotional code WELCOME2026 gives a 100% match on the first deposit up to 500 euros, requires a minimum deposit of 20 euros, and carries a wagering requirement of 45x the bonus value to be completed within 3 days. If your reading of those terms differs from the operator’s, say precisely where and attach the page you are quoting. Keep the language factual and drop adjectives. ADM reads hundreds of these; a clean file gets read properly.
Your concrete next step: send the complaint via PEC to the ADM address listed on adm.gov.it for concessionaire disputes, keep the delivery receipt, and set a calendar reminder for 30 days to check for a reply. If nothing arrives, follow up in writing referencing your protocol number. In parallel, if the sum is significant, a letter from a consumer association (the ones with standing before ADM) often speeds things up. And if the dispute is really about your own play patterns rather than a technical error, use the self-exclusion tools on the conto gioco instead of a complaint. That is the faster route.
